Linux 4.4 has been released This release adds support for 3D support in virtual GPU driver, which allows 3D hardware-accelerated graphics in virtualization guests; loop device support for Direct I/O and Asynchronous I/O, which saves memory and increases performance; support for Open-channel SSDs, which are devices that share the responsibility of the Flash Translation Layer with the operating system; the TCP listener handling is completely lockless and allows for faster and more scalable TCP servers; journalled RAID5 in the MD layer which fixes the RAID write hole; eBPF programs can now be run by unprivileged users, and perf has added support for eBPF programs aswell; a new mlock2() syscall that allows users to request memory to be locked on page fault; and block polling support.
There are also new drivers and many other small improvements. Here is the full list of changes.
That’s something I’ve been waiting for. Having accelerated desktop in KVM is nice. Does it work with Nvidia closed driver used in the host system?
